SENECA Gr. POMEROY, OF KINGS FERRY, NEW YORK.

SULKY-PLOW.

SPECIFICATION formingpart of Letters Patent No. 238,808, dated March 15,1881.

Application filed December 2, 1980.

To all whom it may concern Be it known that I, SENECA G. POMEROY, of Kings Ferry, in the county of Cayuga and State of New York, have inventedcertain new and useful Improvements in Sulky-Plows; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being bad to the accompanyingdrawings, which form part of this specification.

The object of my invention is twofold, relating to mechanism forvertically adjusting the axle on thgspindleuprights of the wheels, andalso to mechanism for securing the plow to the axle.

The several improvements constituting the subject-matter of theinvention will first be described in the specification, and finallyclearly pointed out in the claims.

In the drawings, Figure 1 is a perspective View of the plow. Fig. 2 is aplan view of the same. Fig. 3 is a detail view, showing theinner side ofthe spindle-upright, the vertical guideway, and the connecting parts.Fig. 4 is a detail view of the plate provided with ears, to which thesecondary plow-beam is pivoted.

The spindle-uprighrsAare respectively connected to their appropriatebell-cranks B by links 0. The s 'limlle-uprights are fitted inguidewa-ys, each of which latter is formed by two castings, D,respectively secured to the front and rear sides of the axle E. Eachcasting has its inner side provided with a vertical groove, a, and witha horizontal groove, 11. Each spindle-upright has its inner sideprovided with a longitudinal central rib, 0, projecting laterallytherefrom, this rib being formed with transverse serrations d. The sidesof the spindle uprights fit in the vertical grooves of the casting, andthe sides of the locking-plate F fit in the horizontal grooves. Avertical pin, 6, connects one arm of a bellcrank, Gr, to thelocking'plate, and alongitudinal sliding rod, H, is connected to theother arm of this bell'crank. This rod extends forward and slides in aloop, f, secured to a crossbar, K, a lateral projection, g, being formedon the inner side of the forward extremity of the rod, and forming abearing for the foot of the driver. A spring, L, has one end connectedto the pin 6, and its opposite end connected to (N0 model.)

a horizontal pin, h, having its extremities mounted respectivelyin holeslformed in the two castings. This springtends to maintain thelocking-plate in engagement with the serrations of the spindle-upright.

To adjust the height of the axle the driver presses with his footagainst the lateral hearing g of the sliding rod. The bell-crank isthereby operated so as to overcome the force of the spring and todisengage the lockingplate from the spindle-upright. By throwing, thebell-crank B either forward or backward with his hand the driver canraise orlower the axle to the position required. Then by releasin gthelongitudinally-sliding rod from footpressure the spring throws thelocking-plate into engagement with the spindleupright.

To secure the plow to the axle Iprovide two laterally-diverging hangers,M. Each of these hangers is secured to upturned flanges m of an upperplate, N, the lower side of this plate being provided with a transversesleeve, n, in which a rod, P, is loosely fitted. The extremities of thisrod are mounted respectively in holes formed in vertical ears 1),projecting from a plate, R, this plate being provided with slots r,which permit bolts 8 to secure the plate in lateral adjustment to theupper side of the axle. Plate R is provided at both front and rear sidesof its end portions with depending flanges t, which fit against thesides of the axle and aid in maintaining the plate in position. An arm,S, is secured to the forward end of the plow-beam T, and is also securedto one of the two hangers M of the plow-beam.

The forward end of the arm has a chain, U,

which connects it to the short arm of the bellcrank WV. This bell-crankis pivoted to the tongue Y. One of the hangers M is provided with acatch, 10, adapted to engage with the long arm of the bell-crank W whenthe plow is raised from the ground. The hangers M are secured rigidly tothe rear end of the plowbeam, so that, though the plow is beneath theaxle, its pivotal point of motion is at P, above the axle. In thisrespect it differs from ordinary hangers or bails.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a snlky-plow, the combination, with a vertically-adj ustable baror plate having the 2 asasoe spindlesecured thereto, said plate orbarhaving a rack formed on its rear side, of a springpressedlocking-plate located in horizontal grooves in the guideway and adaptedto engage the teeth of said rack, a bell-crank lever pivoted at one endto the locking-plate, and a rod attached to the other end of thebell-crank lever and extending forward and adapted to be operated by theboot of the driver, substantially set forth.

2. In a sulky-plow, the combination, with a pivotal bracket located overthe axle of diverging hangers M, secured at one end to the bracket andrigid with the plow-beam, and a hanger, S, secured at one end to theplowbeam and having its opposite end attached to one'of the'hangers M,and a bell-crank lever forraising and lowering the plow, substantiallyas set forth.
